| Product Description: 3M™ Stain Resistant Additive SRC-220 is an aqueous fluorinated polyurethane dispersion (PUD) that, when formulated as a penetrating sealer, adds stain resistance and release, and water and oil repellency characteristics to porous surfaces. The SRC-220 concentrate can also be used as an additive to many general coating formulations, and to various construction materials. This product is suitable for both indoor and outdoor use. Suggested Applications: SRC-220 additive can be diluted using water, water-miscible solvents (such as alcohols, ketones, ethylene-glycol-monobutyl-ether, dipropylene glycol monomethyl ether and other glycol mono- or di- ethers), and water-solvent mixtures. When applied at a 2 to 5% concentration and used as a penetrating sealer, SRC-220 additive provides water and oil repellency and stain resistance to porous surfaces such as concrete, grout, unglazed tile, granite, clay, slate, limestone and terra cotta. The sealer is easily applied, dries quickly, is durable and causes no significant change to the appearance of the treated surface. Laboratory tests show that repellency and stain resistance improves when SRC-220 additive is diluted with a water-miscible solvent or a water/solvent mixture, as compared to dilution with water only.
